264 Q. What is the ministry of the church?
A. It is the public preaching of God’s Word, the administration of the sacraments and church discipline–instituted by Christ for bringing to completion the salvation of the elect.
265 Q. Why did God institute the ministry of the church?
A. So that through it he might receive us into his covenant, keep us in it, and really convince us that we are and forever will remain in it.
266 Q. Why do you say that we are received and kept in God’s covenant through the ministry?
A. Because it is the instrument of the Holy Spirit by which he works and confirms in the hearts of the elect the faith and conversion that God requires of us in his covenant.
267 Q. Isn’t the Holy Spirit’s own honor taken away when sanctification is attributed to the ministry?
A. No, for the strength and power by which we are sanctified are all from the divine Spirit; the ministry is merely his instrument by which he moves the souls and hearts of the elect whenever and however it seems right to him–not because he could not do otherwise but because it pleased the divine wisdom, through the foolish preaching of the cross, to save those who believe.
268 Q. What should ministers preach?
A. Nothing but the Word of God contained in the law and the gospel.
269 Q. But how can we be certain that the Word of God is being proclaimed by ministers?
A. If they proclaim the teaching recorded in the books of the Old and New Testaments, and if what they say conforms to the Articles of the Faith and the commandments of God; in short, if they teach us to seek our entire salvation in Christ alone.
270 Q. Isn’t it enough to learn God’s Word privately?
A. It is indeed necessary for our salvation to meditate on it day and night, but if we want to be Christians, we must also make use of the public ministry when we are not prevented by circumstance.
271 Q. Why is this necessary?
A. First, because of God’s command. Second, so that God may be publicly glorified by the whole church in the sight of all people and creatures. Third, so that the unity of the church might be preserved and displayed.
272 Q. What does the Holy Spirit bring about through the preaching of God’s Word?
A. First, he teaches us what God promises us in his covenant and what he in turn requires from us. Next, he persuades us to believe and obey him more and more each day.
273 Q. But how does the Holy Spirit work in us through hearing and meditating on God’s Word?
A. When we learn it for the purpose of believing and obeying him in all things.
